Application filed November 14, 1910.

To all whom it may concern:

Be it known that I, LEE DUNCAN, a citizen of the United States, residingat Muskogee, in the county of Muskogee and State of Oklahoma, haveinvented certain new and useful Improvements in Oil-Burners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in oil burners.

One object of the invention is to provide an improved construction ofoil burner adapted to be employed for heating stoves, furnaces, boilers,and the like and which is especially adapted for domestic purposes.

Another object is to provide an oil burner ofthis character which willbe simple, strong and durable in construction, efficient in operation,and provided with means for catching smoke and soot and for burning thelatter.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings :-Figure 1 is a side view of a burnerconstructed in accordance with the invention; Fig. 2 is a centralvertical sectional view of the same; Fig. 3 is a perspective view of thebase plate or grate of the burner; and, Fig. 4 is a plan view of the oilcup and catch basin of the burner.

In the embodiment of the invention I have provided a base plate or grate1 on which the burner is arranged and supported. The plate or grate 1 ishere shown and is preferably of circular shape and has formed therein aconcentrically arranged circular opening 2. Secured at diametricallyopposite points to the edge of the opening 2 are right angularly formedspacing lugs 8, the inner edges of which are formed on an angle, asshown. On the upper side of the plate or grate 1 and arranged atsuitable intervals thereon are a series of stop lugs, the purpose ofwhich will be hereinafter described.

Arranged in the opening 2 of the plate 1 and spaced a suitable distancefrom the edges of the opening by the lugs 8 is an oil cup 5,

the side walls of which are inclined or flared outwardly toward theupper end of the cup, as shown. Secured to the outer side of the cupadjacent to its upper edge is a catch basin 6 comprising a circularplate 7 having on its upper side an annular upwardly projecting flange8. The flange 8 projects upwardly to the height of the upper edge of theoil cup and thus forms the catch basin by means of which any oiloverflowing from the cup is caught therein and thus increases the sizeof the flame and the heating capacity of the burner. Connected to theinner side of the oil cup near its lower end is an oil supply pipe 9 bymeans of which the oil is fed to the cup from any suitable source ofsupply.

Arranged over the oil cup and catch basin and resting on the plate 1 isa dome-shaped hood 10 having in its upper side an opening 11 which isnormally closed by a cap 13 in the center of which is formed a smalldraft opening 1A surrounded by an upwardly projecting inclined flange15. The cap 13 is provided to afford ready access to the interior of theburner or for lighting in case the wick end 17 is destroyed and also forcleaning and other purposes. The opening 14 in the top of the cap isprovided to facilitate draft through the burner. The lower edge of thehood 10 engages the base plate 1 and is held in a concentric positionthereon by means of the stop lugs A which engage the outer side of thehood, as shown. In the lower edge of the hood are formed a plurality ofburner openings 16 through which the flame from the burning oil in thecup and catch basin is drawn by the draft passing up through the openingin the base plate or grate and through the notches 16 in the hood.Arranged in the catch basin 6 around the upper edge of the oil cup, isan asbestos wick 17, one end of which is brought down and out throughone of the notches 16 in the hood and serves as a means for lighting theburner.

The hood 10 of the burner is provided to catch the smoke and soot and toevenly distribute the flame of the burner which is drawn through theopenings formed by the notches 16 in the lower edge of the hood, thusuniformly heating the hood and burning or consuming the soot caughtthereby.

It will be noted that the parts of the burner are constructed andarranged in such a manner that the same may be readily separated forcleaning or any other purpose and again readily assembled When desired.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended Claims.

Having thus described my invention, what I claim is 1. In an oil burner,a base plate having formed therein an opening, an oil cup arranged insaid opening, a series of spacing lugs adapted to space the sides of thecup from the edges of the opening and to hold said cup in the center ofthe opening, a catch basin arranged around the upper end of the cup, adome-shaped hood arranged over the cup and catch basin, said hood havingin its lower edge a series of notches adapted to form burner openingsthrough which the flame from the burning oil is drawn, and a removablecap arranged on the upper end of said hood.

2. In an oil burner, a base plate having formed therein a centrallydisposed opening, a series of spacing lugs secured to the edges of saidopening, said lugs having inclined inner edges, a tapered oil cuparranged in the opening of said base plate and adapted to engage theinclined edges of said spacing lugs, an annular catch basin arrangedaround the upper end of the oil cup, av supply pipe connected to thelower end of said oil cup, adome-shaped hood arranged over said oil cupand catch basin, said hood having its lower edge engaged with said baseplate and having formed in said edge a series of notches adapted toprovide burner openings, stop lugs arranged on said base plate to holdsaid hood in position thereon, a removable cap engaged with the openupper end of said hood, said cap having formed therein a draft passage,and a wick arranged in said overflow basin and extending down and outthrough one of the notches formed in the lower edge of the hood.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
